windows vista - DVD-RW Drive not recognizing a DVD+R disc

  • Questioner

    I am having trouble burning DVD+R disc's. My OS is vista and i have used this burner and these same discs in the past. I haven't had the need to do so in months and now that i come back to create some backups my DVD/RW drive doesn't recognize a brand new DVD+R disc. These disc are the same ones i have used in the past(Same Pack even). Anyone have any idea what this might be. Maybe a vista upgrade or something that i downloaded in the last few months that could have thrown something off?

    Thanks in advance.

    Probably just a dirty or dying DVD drive: it's the transport/laser/firmware that reads the disk.

    My old DVD drive does not read some DVD writable disks, whether I used XP, XP x64 or now Windows 7.

    DVD-R and DVD+R are different medias, never heard of a DVD-RW recorder working with DVD+R medias... are you sure it ever happened?

    data recovery - Recover badly recorded DVDs
  • CesarGon

    A few years ago (2003-2005) I bought a Sony USB external DVD recorder for my Dell laptop and I used it to burn a lot of discs. Much later, when I tried to use one of these discs, I realised that I could not read it. The disc behaved as if it was scratched or dirty. I tried on a couple of different DVD drives but got the same effect. Sadly, all the discs that I burnt with that recorder suffer from the same problem.

    Edit. When I read one of these discs with ImgBurn, I get lots of unrecovered read errors in multiple sectors, even at 1x speed. The sectors that cause read errors seem to be quite random; it's not always the same one.

    I have no idea what could be wrong with the discs. I doubt that they are scratched or dirty; it would be too much of a coincidence that all the discs that I burnt with that recorder got damaged at the same time. Also, they don't show any physical defects. Is there any way to diagnose what the problem is and, hopefully, recover the contents of the discs?

    Many thanks.

    It's unfortunately very common to get a batch of faulty media. When you originally created the disk, your recording software should have alerted you to the issues. However not all software is created equally.

    I've often seen drives/systems where writing at max speed never works. Also, too high of a load on system resources can lead to the creation of unreadable discs. High temperatures can lead to rapid degeneration of the data-holding part of the disc (this does not need to result in visible warping). CDs and DVDs are no more reliable as a backup medium than a casette tape - and honestly, due to the wide availability of software, drives, and media that are a little too cough consumer-grade, they're often worse.

    You could try IsoBuster, which is specialized on Data Recovery. You might have to try multiple readers and it's not Freeware, but I think the Trial can analyze at least.

    I've had pretty good luck using Nero and reading at the lowest speed. What software have yout tried reading them with?

    I have found that whenever I want recover a damaged DVD(scratched) I can usually recover it by using the slowest read speed and then copying it over to an ISO, although it takes longer I usually get the results I want.

    It may or may not work, just give it a try.
